Abstract
A catalytic converter cartridge comprises multiple square, rectangular or other flat sided catalyst coated substrates, each substrate of which has each of its flat sides covered by a compressible mat material. These multiple mat covered substrates or modules are arranged into a multiple module array enclosed within a metal shell with each module preferably separated from adjacent modules by sheet metal spacers.
Claims23
A catalytic converter cartridge comprising:
- a plurality of catalytic converter modules assembled into an array;
- each of said modules comprising an inner substrate having a front surface, a rear surface and a plurality of flat sides, a compressible mat surrounding all sides of each substrate, each compressible mat surrounding each substrate comprising individual sheets of mat material secured to each flat side of each substrate;
- and
- a sheet metal shell surrounding said assembled modules.
A catalytic converter cartridge comprising:
- a plurality of catalytic converter modules assembled into an array;
- each of said modules comprising an inner ceramic substrate having a front surface, a rear surface, a plurality of flat sides and a compressible mat surrounding all flat sides of each ceramic substrate;
- sheet metal spacers located between and separating each module of the cartridge from an adjacent module;
- and
- a sheet metal shell surrounding said assembled modules.
A method of assembling a catalytic converter cartridge comprising a plurality of catalytic converter modules with each of said modules having an inner substrate having a front surface, a rear surface and a plurality of flat sides and a compressible mat surrounding all sides of each substrate, which method comprises:
- attaching said mat material in the form of flat sheets of mat material to each of the flat sides of said substrates;
- assembling said plurality of mat covered modules into an array;
- placing multiple preformed parts of a metal shell over the assembled array of modules;
- moving the preformed parts of said metal shell inwardly toward one another so as to place said array and said mat material in compression;
- securing together corners of metal shell parts while said array is held in compression.
A method of assembling a catalytic converter cartridge comprising a plurality of catalytic converter modules, each module of which has an inner ceramic substrate having a front surface, a rear surface, a plurality of flat sides and a compressible mat surrounding all flat sides of the ceramic substrate, which method comprises:
- assembling said plurality of modules onto an array;
- placing sheet metal spacers between adjacent modules of said array;
- placing multiple preformed parts of a metal shell over the assembled array of modules;
- moving the preformed parts of said metal shell inwardly toward one another so as to place said array and said mat material of said array in compression;
- securing together corners of said metal shell while said array is held in compression.
